Note that all files were moved to a new directory. The diffs won't be 100% friendly because of this.
Extracted common handling for OAuth on both sides of the connection in order to add a new build status
data handler. This data handler will be used to report build status data. Don't look too closely at the
details of what data is transferred as this will change in the next patch. We will also extract data from
a different page in a slightly different way, but there won't be huge differences.
In particular, we won't look at the /one_box_per_builder page on the master but rather at the transposed
grid (/tgrid) on the build master since we also need the revision number. The regular expressions to
extract the data will be slightly more complex.
